Problems solved by technology

On the other hand, flat-panel TVs are becoming thinner and thinner, but the sound quality is getting worse and worse. This is because the thinner the flat-panel TV, the speakers and sound boxes must be made smaller and thinner; thus, the bass effect is very poor.
In the "Speaker and Sound Box Design Manual" published by Fujian Science and Technology Press in July 2008, the closed sound box (60-67 pages), the open-type sound box (67-77 pages), the passive radiation sound box (77 pages) are disclosed. ~78 pages); These loudspeakers of public technology are either too large in volume and too heavy in quality, or are made small and have poor bass playback effect
Such a subwoofer, also known as a subwoofer, is difficult to meet the requirements of modern audio, let alone be used in flat-panel TVs.

Embodiment 1

[0071] Such as Figure 1A ~ 1C As shown, the loudspeaker 3 of this embodiment is one, installed in the box, and the box is divided into a first cavity 1 and a second cavity 2 by the diaphragm of the speaker 3, the diaphragm faces the second cavity 2, and the diaphragm faces the second cavity 2. The back of the membrane (ie the magnet of the loudspeaker) faces the first cavity 1 . The diaphragm plane of the loudspeaker 3 is parallel to the side walls of the first and second cavities 1 and 2 . Loudspeaker 3 can be a loudspeaker unit, also can be 2~8 loudspeaker units; Loudspeaker 3 can be circular loudspeaker, also can be oval or square loudspeaker, and its size can be 25mm~350mm; Loudspeaker 3 of the present embodiment It is composed of a speaker unit, using a circular speaker with a diameter of 53mm.

[0072] The first bass radiator 4 and the second bass radiator 5 are installed on the box wall of the second cavity 2 correspondingly, the first and second bass radiators 4 and...

Embodiment 2

[0075] Such as Figure 2A-2C As shown, the difference between the present embodiment and the first embodiment is that the diaphragm of the speaker 3 faces the first cavity 1, and the magnet of the speaker 3 faces the second cavity 2, that is, the installation direction of the speaker 3 is just opposite to that of the first embodiment. All the other are identical with embodiment one.

Embodiment 3

[0077] Such as Figure 3A-3C As shown, the difference between this embodiment and Embodiment 1 is that there are two speakers 3 between the first cavity 1 and the second cavity 2, and they are arranged face to face (diaphragm to diaphragm) in the first cavity Between the body 1 and the second cavity 2, the first cavity 1 and the second cavity 2 are separated by the diaphragms of two speakers 3, forming a push-pull speaker drive system. The magnets of the two loudspeakers 3 are respectively located in the first cavity 1 and the second cavity 2 . Each speaker 3 is composed of speaker units, the number of which can be one to four, and the number of speaker units in the two speakers 3 is the same; in this embodiment, each speaker 3 is a speaker unit with a diameter of 53mm. The outer dimensions of the whole subwoofer cabinet will be lengthened accordingly, and the diaphragm areas of the first and second bass radiators 4 and 5 will also be increased accordingly. These two relativ...

Abstract

The invention relates to sound equipment and the low-pitch sound box of a television set, and particularly provides a closed multiple-cavity type low-pitch sound box and a television set with the built-in low-pitch sound box. The sound box comprises a box body, a loudspeaker, a first low-pitch radiator and a second low-pitch radiator. The loudspeaker is arranged in the box body. The interior of the box body is divided into a plurality of cavities by the vibrating diaphragm of the loudspeaker. The first low-pitch radiator and the second low-pitch radiator are disposed opposite to each other on the sidewall of any one cavity. All the other cavities, except the above cavity with the first low-pitch radiator and the second low-pitch radiator, are in the form of closed cavities. The vibrating diaphragm and the magnet of the loudspeaker are arranged in the box body and are not oriented towards the audition space. Therefore, no medium-and-high-pitch sound is directly radiated to the audition space, and it is ensured that the obtained low-pitch sound is pure and clear.

Description

technical field [0001] The invention relates to a sound box and a subwoofer box for a television set, in particular to a closed multi-cavity subwoofer box and a television set with the subwoofer box built in. Background technique [0002] As we all know, in recent years, with the advancement of technology, people have higher and higher requirements for the sound quality of audio playback, and require smaller and smaller volume and weight. On the other hand, flat-panel TVs are getting thinner and thinner, but the sound quality is getting worse and worse. This is because the flat-panel TVs are thinner, and their speakers and sound boxes must be made smaller and thinner; like this, the bass effect is just very poor. In the "Speaker and Sound Box Design Manual" published by Fujian Science and Technology Press in July 2008, the closed sound box (60-67 pages), the open-type sound box (67-77 pages), the passive radiation sound box (77 pages) are disclosed. ~78 pages); These loudsp...
